BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, commercially grown as a pot-type Chrysanthemum and hereinafter referred to by the name ‘Dark Orange Yocupertino’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of the Chrysanthemum×morifolium cultivar ‘Yocupertino’, disclosed in U.S. Plant Pat. No. 17,489. The new Chrysanthemum was discovered and selected by the Inventor in a controlled greenhouse environment as a single flowering plant within a population of plants of ‘Yocupertino’ in December, 2004, in Fort Myers, Fla.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttings was first conducted in a controlled greenhouse environment in Fort Myers, Fla. in March, 2005. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dark Orange Yocupertino’. These characteristics in combination distinguish ‘Dark Orange Yocupertino’ as a new and distinct pot-type Chrysanthemum cultivar:

-   -   1. Upright, outwardly spreading and uniformly mounded plant         habit.     -   2. Strong and vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored foliage.     -   5. Uniform, freely and early flowering habit.     -   6. Daisy-type inflorescences with dark bronze-colored ray         florets.     -   7. Excellent postproduction longevity with inflorescences         maintaining good substance and color for about five weeks in an         interior environment.

Plants of the new Chrysanthemum differ from plants of the parent, ‘Yocupertino’, in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flower more uniformly than         plants of ‘Yocupertino’.     -   2. Plants of the new Chrysanthemum and ‘Yocupertino’ differ in         ray floret color as plants of ‘Yocupertino’ have golden         bronze-colored ray florets.

Plants of the new Chrysanthemum differ from plants of Chrysanthemum×morifolium ‘Yellow Yocupertino’, U.S. Plant Pat. application Ser. No. 12/214,247 primarily in ray floret color as plants of ‘Yellow Yocupertino’ have bright yellow-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Yoauburn’, disclosed in U.S. Plant Pat. No. 12,526. In side-by-side comparisons conducted in Fort Myers, Fla., plants of the new Chrysanthemum primarily from plants of ‘Yoauburn’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum flowered one week earlier         than plants of ‘Yoauburn’.     -   2. Plants of the new Chrysanthemum and ‘Yoauburn’ differed in         ray floret color as plants of ‘Yoauburn’ had orange         bronze-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum. This photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum. The photograph comprises a side perspective view of typical flowering plants of ‘Dark Orange Yocupertino’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in Leamington, Ontario, Canada during the autumn in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial pot-type Chrysanthemum production. During the production of the plants, day temperatures ranged from about 21° C. to 27° C., night temperatures ranged from about 17° C. to 19° C. and light levels ranged from 4,000 to 6,000 foot candles. Four unrooted cuttings were directly stuck in 15-containers, exposed to long day/short night conditions, and pinched about three weeks later. At the time of the pinch, the photoinductive short day/long night treatments were started. Plants used in the photograph and for the description were grown as natural sprays and were eleven week old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
